This is a fix for crrev.com/c/1496002, which was reverted because of a
1-character mistake. The rest of the CL message is copied from the
original:

Previously the wrapper script would only be used for coverage builds
that required selective instrumentation of specific files. Now it
will also be used for any coverage builds.

Since the script's job is to remove flags from files that shouldn't
have them the default_coverage config now adds to cflags even in a
CQ build.
